Poisoning is a common and potentially life-threatening injury. Most poisonings in young children are unintentional, whereas poisonings in other age groups may be unintentional or intentional (e.g., suicide attempts, substance abuse, or medication misuse). The majority of poisonings are a result of ingestion of a substance, but poisonings may also occur after a toxin is inhaled or comes in contact with the skin and eyes. Bites and envenomations are other potential sources of toxin exposures. First aid for poisonings
